Let's divide 86370134 by 25
We're looking to find how many times 25 goes into 86370134.

Let's proceed to step 1:
The number 25 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 25

Step 2:
86 divided by 25 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 75 from 86 and we're left with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 25

Advancing to step 3:
113 divided by 25 is 4 with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 100 from 113, we get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 25

Advancing to step 4:
The number 25 fits into 137 5 times, leaving a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 345.0
If we take 125 away from 137, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 25

Let's proceed to step 5:
If we divide 120 by 25, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 3454.0
If we subtract 100 from 120, we get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 25

Going ahead to step 6:
25 can be fit into 201 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 34548.0
The remainder is 1 after subtracting 200 from 201.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 25

Moving on to step 7:
13 divided by 25 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 345480.0
Subtract 0 from 13 to get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 25

Step 8:
25 goes into 134 5 times with a remainder of 9.
The next digit of our result is 5. 
Result so far: 3454805.0
Subtracting 125 from 134 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
25 goes into 90 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3454805.3
If we take 75 away from 90, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 25, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 3454805.36
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3454805.36
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3454805.36
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3454805.36 with a remainder of 0.0.
